In terms of sodium, The ½ Pound Thickburger El Diablo burger contains 2790 milligrams, meaning you are eating more than your entire recommended daily sodium intake in one burger -- and you haven’t even added the fries yet.

“The burger also only has four grams of fibre -- in Australia the recommended daily intake for fibre is 30 grams,” McLeod said. “So that’s only one-tenth of your fibre from one of your largest meals of the day.”

“From my perspective, with all the benefits that come from a high-fibre diet, it’s just not enough for one meal.”

If you can feel your arteries clogging up already, hold on tight.

“The burger also contains more fat than you’re supposed to have in your whole day and most of it is saturated fats -- which is the one you’re supposed to have little of,” McLeod told HuffPost Australia.

When compared to a McDonald's Big Mac -- which contains 493 calories, 859 milligrams of sodium and 26.9 grams of fat -- the Carl’s Jr burger pales in comparison.

“I’m not here to be the food police, but unfortunately, the people who are eating this thing often don't have an understating of what they're actually eating,” McLeod said.

“Especially when you look at different statistics about heart diseases and obesity, it’s quite sad, really, because burgers like this are making it even harder for people who are already struggling.”
